Basic Syntax
Python is a high-level, interpreted language. It is called high-level because it is abstracted from the details of the computer’s hardware and operating system. Python is interpreted, meaning that it is executed at runtime by the interpreter, rather than being compiled into a standalone executable.
The basic syntax of Python consists of statements, which are lines of code that perform a specific task. Statements are usually terminated by a new line, but they can also be terminated with a semicolon (;).
In Python, indentation is significant and is used to denote blocks of code. Indentation is done using spaces or tabs, and it is important to be consistent with the use of either spaces or tabs throughout a program.
Here is an example of a simple Python statement:
print("Hello, World!")
This statement prints the string “Hello, World!” to the console.
Variables
In Python, a variable is a name that refers to a value. Variables are used to store data in programs.
To create a variable in Python, you simply assign a value to a name. For example:
x = 10
y = "Hello, World!"
In the above example, x is a variable that refers to the value 10, and y is a variable that refers to the string value "Hello, World!".
In Python, the type of a variable is determined by the value it refers to. The type of a variable can change during the execution of a program.
